CVE-2019-1563

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

• ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
• AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
• Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

3.83% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 89.6% of scored records. A rank, not a probability.

NVD base score

3.7 (CVSS v3.x), scored by the NVD independently of the CNA.
